What does squamule mean?
A squamule is a small scale, particularly one of the numerous overlapping scales covering a snake or another reptile. The term is chiefly used in zoology, herpetology, and anatomical description, where researchers may discuss the shape, texture, or arrangement of squamules on different parts of an animal's body. A squamule should not be understood as an entirely different structure from a scale in the general sense; it is a small or reduced scale viewed more precisely. The word can also be useful in descriptions of reptilian anatomy, especially when distinguishing dorsal scales on the back from ventral scales along the underside. Its specialized meaning makes it less familiar than the ordinary word scale, but it provides an exact term for describing the smaller elements of reptilian skin.

A squamule is a reptile's smallest-scale clue: it is a diminutive of the Latin word for an entire scale.
